Answer / ds
In Stage variable:
stage_variable3 <map> stage_variable1
if column=stage_variable1 than 0 else 1 <map>
stage_variable2
column <map> stage_variable3
Put stage_variable2 as constrain to target stage.

Answer / amit
using hash partition technique, we can bring duplicate data(based on key columns) in one partition. Then in stage constraints filter out data with setting @inrownum = 1.
This will remove duplicate in transformer stage.
